Towards the end of 2011, Pusey, Barrett and Rudolph derived a theorem that aimed to show
that the quantum state must be ontic (a state of reality) in a broad class of realist approaches …

At a fundamental level, the classical picture of the world is dead, and has been dead now for
almost a century. Pinning down exactly which quantum phenomena are responsible for this …

Quantum mechanics is an outstandingly successful description of nature, underpinning
fields from biology through chemistry to physics. At its heart is the quantum wavefunction, the …

According to a recent no-go theorem [M. Pusey, J. Barrett and T. Rudolph, Nat. Phys. 8, 475
(2012) NPAHAX 1745-2473 10.1038/nphys2309], models in which quantum states …

The superposition principle is fundamental to the quantum description of both light and
matter. Recently, a number of experiments have sought to directly test this principle using …

The emergence of realistic properties is a key problem in understanding the quantum-to-
classical transition. In this respect, measurements represent a way to interface quantum …

There is a longstanding debate on the metaphysical relation between quantum states and
the systems they describe. A series of relatively recent ψ ψ-ontology theorems have been …

Magnesium ions have many cellular actions including the suppression of the excitability of
neurons; however, the depolarization effect of magnesium ions seems to be contradictory …

Abstract The Barrett–Cavalcanti–Lal–Maroney (BCLM) argument stands as the most
effective means of demonstrating the reality of the quantum state. Its advantages include …
